Abstract

Beschrieben wird ein Schalter (10) mit einem ein temperaturabhängiges Schaltwerk (11) aufnehmenden Gehäuse (12), das ein erstes Gehäuseteil (15), an dessen innerem Boden (25) eine mit einem ersten Außenanschluß (23) verbundene erste Elektrode (24) angeordnet ist, sowie ein das erste Gehäuseteil (15) verschließendes zweites Gehäuseteil (14) aufweist, das eine mit einem zweiten Außenanschluß (22) verbundene zweite Elektrode umfaßt. Das Schaltwerk (11) stellt in Abhängigkeit von seiner Temperatur eine elektrisch leitende Verbindung zwischen der ersten und der zweiten Elektrode (24, 20) her. In dem Gehäuse (12) ist geometrisch und elektrisch zwischen den beiden Elektroden (20, 24) ein Parallelwiderstand (33) angeordnet.

Figure 00000001
A switch (10) is described with a housing (12) which accommodates a temperature-dependent switching mechanism (11), which has a first housing part (15), on the inner bottom (25) of which a first electrode (24) connected to a first external connection (23). is arranged, and has a second housing part (14) which closes the first housing part (15) and which comprises a second electrode connected to a second outer connection (22). Depending on its temperature, the switching mechanism (11) establishes an electrically conductive connection between the first and the second electrode (24, 20). A parallel resistor (33) is arranged geometrically and electrically in the housing (12) between the two electrodes (20, 24).
